Behavioral and Pharmacologic Treatment of Binge Eating and Obesity: Acute Treatment
November 23, 2022 updated by: Yale University
Behavioral and Pharmacologic Treatment of Binge Eating and Obesity
This study will test the effectiveness and relative efficacy of behavioral and pharmacologic treatments, alone and in combination, for the treatment of binge eating disorder (BED) in patients with obesity.
This is an acute treatment comparing behavioral weight loss alone or in combination with naltrexone/bupropion medication.
Study Overview
Status
Active, not recruiting
Conditions
Detailed Description
Binge eating disorder (BED), the most prevalent formal eating disorder, is associated strongly with obesity and bio-psychosocial impairment.
Improved treatments for obese patients with BED are needed that can produce sustained clinical outcomes and promote weight loss.
This study (acute treatment stage) aims to test the effectiveness of behavioral weight loss (BWL) and pharmacological treatment with Naltrexone/Bupropion (NB; a recently FDA-approved anti-obesity combination medication), alone and in combination, for the treatment of BED in patients with obesity.
The acute treatment stage stage RCT will provide new findings regarding the effectiveness of NB medication and whether this specific combination of BWL and NB medication is effective for patients with obesity and BED.
N=160 patients with BED and obesity will be randomly assigned (double-blind) in a balanced factorial (2 X 2) design trial, to one of four 16-week interventions: BWL+NB, BWL+Placebo, NB, or Placebo.
This study will produce important new information about the relative efficacy of BWL and this recently FDA-approved anti-obesity (NB medicine), alone and in combination, for BED in patients with obesity.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: NB medication
Participants randomly assigned to this arm will receive 16 weeks of NB medication.
NB medication will combine naltrexone sustained-release (SR, 32 mg/day) combined with bupropion SR (360 mg/day) taken daily in pill form.

Experimental: BWL + NB medication
Participants randomly assigned to this arm will receive 16 weeks of Behavioral Weight Loss (BWL) counseling and NB medication.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Binge Eating Frequency (Continuous)
Time Frame: Post-treatment (4 months)
|
Binge eating will be assessed by interview and self-report and the primary outcome is frequency.
Frequency will be defined continuously (analyzed dimensionally).
|
Post-treatment (4 months)
|
Body Mass Index (Percent Weight Loss)
Time Frame: Post-treatment (4 months)
|
BMI is calculated using measured height and weight.
Percent weight loss, where negative values represent proportional weight loss, is calculated as the difference between weight at post-treatment and baseline weight, divided by baseline weight.
By definition, all participants have 0% weight loss at baseline.
|
Post-treatment (4 months)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants Meeting Response Criteria
Time Frame: Post-treatment (4 months)
|
Binge eating frequency will be assessed by interview and self-report.
Frequency is defined categorically (response to treatment or non-response to treatment).
Response to treatment is defined as a 65% reduction in binge eating frequency in past month, compared to baseline.

Post-treatment (4 months)
